[OMC-Boats] 67 Explorer Foam

The foam is "closed cell foam" meaning it should not take water into the
little bubbles of foam (for lack of a better explanation) and become
waterlogged. The question arises how much water is logged into the floor of
your boat and no one can answer that without removal of the foam. I would
GUESS that there are a couple gallons of water in there which translates
into added weight. That probably is no problem except when you close that
all up will you get rot to the undersurface or your wood? Probably not in
your lifetime. I had similar condition with my Rogue and refoamed the floor
with a two part foam that is like the original foam and is easy to get - the
process is tedious and I am not sure worth all the effort. The foam under
the engine compartment can't realistically be reached without taking the 2
boat halves apart The foam is necessary for floatation in case of
catastrophy and also provides hull stabiltiy and deadens sound. My hull also
had longitudinal stringers embedded in the foam - these had some rot at
their forward ends. You can dig around in the foam and tell somewhat how
much water is in there. I think the center locker is a good idea. I have
always liked that helm forward design. TK----- Original Message -----
